A hybrid method,which combines the line method with the method of equivalent transmission lines, for calculating the dispersion of planar waveguide structures is presented.

Abundant explicit and exact plane wave structures, such as solitary waves, periodic waves, Jacobi elliptic function waves and others exect traveling plane wave, are derived.

Laser beam addition of planar waveguides with fractional self-imaging

In order to improve the detection sensitivity and increase the response speed of the biosensor,based on the theory of planar waveguide,the zone energies of the evanescent fields in the single mode and multimode of the planar optical waveguide were compared under the same condition by using the principle of the evanescent field applied to the biosensing field.

GeO2-SiO2 planar waveguide technology is reviewd in this paper in terms of its history andprospects and application in integration optics.

A core-cladding waveguide structure of lithium niobate single crystal fiber is achieved by using MgF_2 firstly as a diffusion source for Mg-ion indiffusion.

Aiming at the high-power laser,the vertical far-field divergence angle was reduced by the very narrow waveguide and the mode expanding waveguide structures,a simplified model of the far-field distribution of quantum-well lasers with a very narrow waveguide structure and the theoretical value of the vertical divergence angle were achieved,the vertical divergence angle was reduced to 2.
